I took the Khimera out kayaking and loved the low profile foam vest which offered ease of movement. I pulled the manual pull tab to test the inflation functionality and it really worked well and I still could move easily. I feel safer knowing I can always get extra buoyancy if I need it. When pressing the deck and re-entering my kayak, I just released some air from the oral inflation tube which really helped get my centre of gravity down making it safer and easier to get back in. I like the option of the oral inflation to customize the buoyancy too! Great all round vest that I can also take fishing or standup.
